CABLE HANGER.

Application filed April 5,

My invention relates to improvements in cable hangers and has for itsprimary object a cable hanger which is designed to be suspended from amessenger wire and which is provided with a longitudinally extendingcradle or seat for the cable so that a contin uous longitudinal supportwill bev provided for the cable instead of the point support as is thecas'e with the present style of wire and cable hangers. V

A further object is to construct a cable hanger which can be readilyattached. and detached to existing lines without the aid of tools, andwhich has substantially a V shaped longitudinally extending cable seator "cradle. This peculiar shape of cradle permitting its readyapplication to cables of various sizes and giving substantially a longlongitudinal support for the cable.

In the drawings:

Fig. 1 isa bottom plan view ofm'y device showing the same attached to amessenger wire;

Fig. 2 is *a side elevation of the same;

Fig. 3 is an end elevation viewed in the direction of the arrow in Fig.1; I

Fig. 4 is a fragmental perspective view of the clamping and supportinghook; and

Fig. 5 is a fragmental perspective viewof the supporting hook.

In the construction of my device I employ a. hanger which is preferablymade from spring wire, one end of which is provided with a snpp'ortii'ighook 6. Formed integral with the hook '6 is an outwardly bowed arm 7-,this arm extends downward to a point 8, which point is designed to bedirectly be neath the messenger wire. When the hanger is attached fromthe point 8 the wire extends upwardly forming an end or arm 9, this armis bent upward at an angle so as to form a relatively sharp bend at thepoint 8. The portion -9 is then bent so as to form a side memberorfinger 10 the side member extends. in a direction parallel to themessenger wire 11. The side 10 is then bent so as to form. an end 12which parallels the end or arm 9. Formed integral with the arm 12 andparallel to. the side 10 is a bottom member 'or'finger 13,.this memberhas formed integ ral therewith an end 14'which is parallel to the ends 9and. 1-2. This arm or end 14 is also upwardly inclined (see Figs. 2 and3). Formed integral with the arm 14 is a side or finger 15 which isparallel to the side 10 and bottom 13. The side or finger 1% has end1924. serial no. 704.360.

16 formed integral therewith which is parallel to the end 14 and lies inthe same plane. The end 16 extends downwardly to a point 17 from whichpoint extends a bowed arm 18., this arm being bowed in theopp'ositedirection to the arm 7. The arm 18 is ;pro vided with a horizontallyextending portion 19 which is so bent as to pass beneath the messengerwire, and on the end of the portion 19 is formed a clamping andsup-porting hook20. V

,It will be noted from Fig. 3 that the sides or 10 and 15 are raisedsufficiently above thebottom 13 so that when a cable is placed thereon,it will be held clear of the arms 7 and 18. The sides or fingers 10 and15 bottom or finger 13 and ends 9, 12, 14 and 1 6 form a cradle or cableseat which is substantially V shaped or angular in cross section. Thisfeature :not only centers the cable over the seat but will also preventits rolling around and shifting laterally therein, and at the same timewhen the cable is placed within the seat it will be supportedlongitudinally either by the bottom 13 or by the sides- 10 and 15. Inthis way the point contact with the cable is prevented and conse'quentlythe 'dangerioi kinking for sagging down is practically eliminated. I

It will be noted from Fig. 1 that the hook 20 is arranged at an angle tothe messenger wire so that it will have a clamping eliect thereon.

In attaching my device the hook 20 is first placed over the messengerwire 11 when this is done the hook 6 will be laterally removed from themessenger wire and on the side opposite. from that shown in 2. The hook6 is then brought down underneath the cable and over to the other side.This action causes the hook 20 to twist on the cable and thus set uptorsion and gripthe messenger wire on two sides. The hook 20 is thenraised sufficiently toclear the messenger wire and brought over so thatwhen it is released it will-grip the wire. This flECtlOTLGHJUSGS torsionto be set up in the arm 19 which grips the messenger wire on the bottomandv forces the top o1 the hook against the top of the messenger wire;The torsion set up in the member 19 also exerts a downward pull ontheh'ook 20 which prevents it from acciden-tally lifting 'oif, eventhough no cable is located within the hanger thus it will be seen thatthe clamping and supporting hook not alone supports the arm 18, but alsohas a clamping action on the top, bottom and both sides of the messengerwire thus effectually preventing the hanger from creep- 1n %Vhile I haveshown the cradle as being substantially rectangular in plan, still thismay be varied to various shapes without departing from the spirit of myinvention, the essential feature being an elongated longitudinallyextending seat or cradle which is angular or V shaped in cross sectionand which is so constructed as to have substantially a long longitudinalsupporting surface and at the same time prevent the cable fromcontacting with the supporting arms. In other words, eliminate allpossibility of point contact.

It is not essential that the bottom member or finger 13 be parallel tothe sides 10 and 15 but it may be arranged at an angle thereto, Andfurthermore if found necessary or desirable the side members 10 and 15need not be raised above the arms 7 and 18 but terminate in the sameplane so that these arms will also contact with the cable. Theangularity or curvature of the seat or cradle member may also be variedwith reference to its depth without departing from the spirit of myinvention Having fully described my invention, what I claim is 1. Acable hanger constructed of a single piece of resilient materialcomprising abody portion provided with a substantially V- shaped cablesupporting seat, said seat liaving plurality of contact points for thecable adapted to engage and support the cable on its opposite sideswhereby the cable is prevented from lateral movement in its seat, spacedapart arms carried by the body portion so that the hanger may be appliedto an existing cable without spreading said arms, the arms beingprovided at their ends with gripping means for engagement with amessenger wire, at longitudinally spacedapart points.
